To all whom it may concern FRANK A. GRAHAM, OF BUFFALO, NEW YORK.

BOX-MAKING MACHINE.

Be it known that I, FRANK GRAHAM, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Box-Making Machines; and do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, tion. 1

This invention relates to new and-useful improvements in box making machines and the object in view is to produce a simple and efiicient apparatus of this nature so constructed that a blank from which a box is made is trimmed, creased and cut at proper locations where the blank'is to be bent to form the sides of the box.

The invention consists of various details of construction, combinations and arrangements of parts which will behereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a top plan view of the apparatus. Fig. 2 is a side elevation. Fig. 3 is a detail view in elevation showing intermeshing gears which operate the cutter rollers. Fig. 4 is a sectional view on line 44 of Fig. 1 looking in the direction of the arrows. 5-5 of the arrows. view of a Fig. 1 looking in the direction of part of an adjustable guiding member. .Fig. 7 is a similar view showing an adjustment of one feature of the invention. Fig. 8 is a detail perspective of a blank havihg two longitudinal scored lines formed therein by the apparatus. Fig. 9 is a view of the complete blank preparatory to its being folded to box form, Fig. 10 is a view showing the blank folded to form four sides of a box, and Fig. 11 is a detail in elevation of a part of the invention.

in the frame. and upon which a loosely mounted driving wheel 4 is journaled, provided with a clutchcollar 5 which is driven by means of the lever 6 into or out of opera tive relation with the shaft 3,'and hand wheels 3 are fixed to the opposite ends of the shaft 3 for convenience in rotating the same manually if desired for any purpose.

'Said shaft 3 has keyed thereto a gear wheel 7, shown in Fig. 2 of the drawin s, and which meshes with a gear wheel 8 xed to the shaft 9, which latter is journaled in suitable bearings in the frame.

Shafts 11 and 12 are j ournaled, the former the frame, as shown clearly in Fig. 2 of the drawings, and gear wheels 13 and 14 are keyed respectively to the shafts 11 and 12 and intermesh with each other. A transmission gear. 14:, ournaled upon a shaft 15, is in mesh with thetwo gear wheels 8 and 13 forming means for transmitting motion from one to the other. A beveled gear 16 is keyed to the shaft 12 and is in mesh with a beveled gear 17 mounted upon a shaft 18 journaled in suitable bearings. A gear wheel 20 is fixed to the shaft 18 and meshes with gear wheels (not shown) fixed to the shafts 21'and 22 respectively, which latter are shown. in Fig. 3 of the drawings. The gear wheels (not shown) which are fixed to the shafts 21 and 22 mesh with shafts 23 and 24, see Fig. 1 of At the opposite ends of the the shafts 29 and 30.respectively, and a gear wheel 31, shown in top plan view Fig. land to the shaft l8, meshes with the two gear wheels 25 and 26, as shown plainly in Fig. 3. It will be understood that the arrangement of gear wheels shown in Fig. 3 at theouter ends of the shafts 29 and 30 are similar to the gear wheels before-described at the inner end of the shaft. Fixed to the two shafts 30 and 22 are the circular beveled cutting knives 32 and 33 respectively, which are adapted to trim the opposite edges of the blank 34 which is shown in Fig. 1 upon the table of the machine with portions of the blank partially trimmed. Circular-outlined beveled creasing members, designated by numerals 36 and 37, are fixed respectively to the shafts 29 and 21 and serve to form the longitudinal creased lines, designated in the drawings by numeral 38.

- plates through the pivot 44 The means for guiding the blank 34 after it passes underneath the rollers which receive the longitudinal creases 38 after the opposite sides have been trimmed by the knives described, consists of a bar 39, shown in Fig. 1, adjustably held by means of bolts 40 to the reciprocating plates 41 which have longitudinal movements in the grooves 42 in the table or top of the apparatus. Projecting from the under side of each of said 41 is a lug 43 having a link 44 pivoted thereto, which in turn is pivotally connected to the crank arm 45 fixed to the shaft 46, journaled in suitable hearings in the there are two of said links and arms 44 and 4.5 respectively fixed to the plate 41. A crank arm 47 is fixed to the shaft 46 and has pivotal connection with a pitman 48 which in turn is pivotally connected to the wrist pin 49 secured to a disk 50 fastened to the shaft 3, thus affording means whereby, as the shaft 3 is moved, a reciprocating movement will be imparted to the plates 41 which carry the adjustable feeding bar 39, causing the blank, after it has been scored longitudinally, to feed sidewise toward that part of the apparatus where the transverse cutting lines are scored and slots cutintothe oppositeedges thereof. As the blank passes between the rollers 29 and 21, it is guided between the adjustable strips-51' and 52, de-

- Fig. 1, Fig.

. jects below the tails of portions of which are shown in-Figs. 6 and 7 of the drawings, andv which are provided with longitudinal slots 54 and 55 through which a bolt 57 passes. Said strips are disposed at an inclination, as shown 1n 7 3 illustrating more clearly a portion of one ofthe strips, and a plate 58 is fastened to one of the strips 51 and prolower'edge thereof and is adapted to form means for pushing the blank sidewise to receive the transverse scored lines. A guide strip 60, shown in top plan view in Fig. 1, is provided with a longitudinal slot 61, as shown in Fig. 7, and a wedge-sha ed block 62 is bolted to ,one end of the gui e strip51, serving to hold thelatter at an inclination, and an an le plate 63 is secured to said wedge-shape block and has an inverted hook-shaped portion "64 tions.

- Fig. 1 and serves as which fits over and is movable upon the upper edge of the strip 60, an adjusting screw 65 passing through the angle plate and also through the slot 61 and upon which athumb nut.66 is adapted to be fitted to -hold the strips 60 and 51 in relatively adjusted posi- Upon reference to Fig. 6 of the drawings, it will be noted that an angle. plate 67 "is fastened to a wedge-shaped block 68 "and which plate 67 is shown in top plan view in a the strip asit is cut by the circular knives 32, said plate 67 being bolted .to the wedge frame. It will be noted that means for separating tudinal slot in a guide strip 72, similar to the guide strlp 60 before described. The

inner ends of the two strips 60 and 72 are connected to a bar 73 which has a longitudinal dove-tail recess 74 therein, as shown in Figs. 1 5 and 11 of the drawings. Theinner en s of the two strips 60 and 72 have angle plates 75 fixed thereto and a portion of each of said plates 75 is apertured for the reception of a setscrew 76, forming means whereby the apertured portion of the plate may be held in a recess in an adjustable block 77, which blocks are similar to the blocks 78 and 7 9 which carry the adjusting screws 80 upon which the thumb nuts 81 are mounted to hold the blocks in different relative adjustments within the member 73. Each of said blocks 78 and 79 is recessed for the reception the former of which is beveled as at 81 at its lower end and serves to hold the blank down against the surface of the tablewhen moved laterally and the other member is forked and has a roller journaled in the ends thereof and serves to frictionally engage the upper surface of the blank as it moves sidewise. The two members 82 and 83 are held in fixed positions in the recess s in which they are mounted through the medium of the screws 86.

Referring to Figs. 1 and 5 of the drawings will be seen segment saws 89 with blank spaces intermediate'their ends and upon opposite sides of each segment saw are the disks 90 which are bolted to the saws support the blank while of the two members 82 and 83,

of the blank, said disk 7 30., upon the former of which the beveled scoring disks are mounted and which form the longitudinal scores in the blank. 'The cutting knives 32 trim the opposite edges, as shown,'and the blank as it is fed forward is guided between the strips 51 and 52 which.

are disposed at an inclination, thus causing the -blank-to fall down upon the surface of the table. The feeding bar 39 will cause the blank to be fed laterally after the longitudinal scored lines have been formed. As the blank .passes underneath the anti-friction rollers-85 and the guiding members 82, it is held down to the table where, as it passes 40 the edge of 'a blank, means for scoring underneath the scoring members 97, the transverse scored lines will be formed. At each revolution of the shaft 9 carrying the saw teeth, slits will be formed in the opposite edges of the blank in alinement with the longitudinal score lines. Through the medium of the adjusting means, it will be noted that blanks of various'sizes may be scored and slits formed forthe purpose of making 10 boxes of different sizes.
